Opening Three-Bids -- for weak hands with long, strong suits.


An opening Three-Bid, called a preempt, shows a weak hand can take five or more tricks if your suit is trumps, but is unlikely to take any tricks in any other suits. To open (or overcall) a Three-Bid, you should have:

Always consider the vulnerability. If you're vulnerable (your side has made a game), the penalties for not making your contract are much higher. Open a vulnerable Three-Bid only if you have strong 7-card suit. Here are some example hands:

973   3   KQJ942   Q43 -- Open 3D (but pass if you're vulnerable).

AKJ10743   5   8654   8 -- Open 3S at any vulnerability.

A6   J943   Void   KJ86432 -- Pass. You have too much strength outside your suit to open 3C, which would make it almost impossible to find a heart fit if you have one. This hand may be easier to describe later (with an overcall, or a response to partner's opening bid).

AKJ10763   82   QJ54   Void -- Open 4S. This has too much playing strength for 3S.

K84   AK108654   86   4 -- Open 1H. This hand is too strong for a 3-bid.

Once you make a Three-Bid, you've described your entire hand, so you shouldn't bid again unless partner makes a forcing bid. The only ways partner can force are by bidding a new suit, by cuebidding the opponent's suit, or by asking for aces.


Responding to a Three-Bid

If partner opens a Three-Bid, it's up to you to place the contract. With a weak hand and no fit, you pass. With a stronger hand, don't count just points -- what's important is the number of tricks you can take. Consider the vulnerability and try to visualize partner's hand, then count your potential tricks.


The Sacrifice

A Three-Bid can be valuable when you want to "steal" the hand with a sacrifice. If the opponents bid game, you bid higher in partner's suit, hoping to get a smaller minus score than if the opponents had made game.

For a sacrifice to be profitable, your hand must be weak enough in high cards for you to be sure the opponents can make a game. Your hand must also be strong enough in playing tricks and trump support for you to be sure you won't be set more than two (sometimes three) tricks.

The best time for a sacrifice is when you are not vulnerable and the opponents are-when their game would give them a 700-pt. rubber. You can then afford to be doubled and go down as many as three tricks (losing 500 pts.) for your sacrifice to be profitable.


AT THE TABLE

You are not vulnerable. Partner opens 3S and the opponent on your right passes. What is your bid?

J87   9   AK72   AJ1054

4S. Your spade support will help partner take at least 5 (or as many as 7) trump tricks, plus your three top tricks in the minor suits. It's also likely that he can score one or two more tricks by trumping hearts in your hand or setting up your diamonds.

86   KQJ5   KJ65   AJ3

Pass. This hand has more points than the previous example, but much less playing strength. You know partner has no outside aces or kings, so you may have at least three side-suit losers (or perhaps five!), as well as a possible spade loser or two.

J982   4   A10432   876
4S. You have no real hopes of making this contract, but your excellent spade support and singleton heart guarantee that partner won't go down very many tricks. You know the opponents are short in spades and that they can surely make at least 4H or 5C (or even 3NT) if you let them bid it. Your 4S bid is an "advance" sacrifice-it uses up bidding space before the opponents can find their contract. And if partner holds a hand like AKxxxxx xxx xx x, you'll even make your game.
You are vulnerable. Partner opens 3C and the opponent on your right passes. What is your bid?
AJ10   A53   Q1054   A92

3NT. Partner is vulnerable, so he should have a good 7-card suit (you have the ace, so he must have at least the KQ). You can therefore count 9 tricks -- 7 clubs and 2 aces -- and you have a "stopper" in diamonds if the opponents lead that suit.

5   A94   AKQ1076   A53
6C. You know the opponents have the ace of spades, but you can be almost sure that this is the only trick partner will lose. Count your possible tricks. Partner will take at least 6 or 7 club tricks (he should have the KQ of clubs), 1 heart and 3 diamonds right off the top. He should be able to find 2 or 3 more tricks by trumping his spades in your hand or by running your diamonds.
